Lesson 1: Follow one sale end to end
Start with a familiar sale rather than a product brochure. Write down who enters the order, where the customer pays, which device or page collects payment, how the receipt is delivered, and where the owner checks the result. Authorization, settlement, and the bank deposit are different events; use your provider's reports to connect them rather than assuming every approved sale is already in the bank.
- Choose one counter sale, one remote sale, and one refund to trace.
- Record the order reference, payment reference, batch, and deposit reference without copying card details.
- Identify who investigates a mismatch and which report is the source of truth.
